Ceti Alpha (also known as Menkar or Alpha Ceti) is a star with an associated star system of five planets and an extensive asteroid belt. Ceti Alpha is located in or near Federation space in the Beta Quadrant's Mutara sector, and is visible from Sol in the Cetus constellation.
In 2267, the USS Enterprise deposited Khan Noonien Singh and the survivors from the SS Botany Bay on Ceti Alpha V, following their attempt to seize control of the Enterprise. Although it was a lush planet that they could thrive upon, that all changed six months later when Ceti Alpha VI exploded and destroyed all terrain and animal life on Ceti Alpha V. (TOS episode & novelization: Space Seed; TOS movie, novelization & comic adaptation: The Wrath of Khan; ENT episode: "Twilight"; TOS - The Eugenics Wars novel: To Reign in Hell: The Exile of Khan Noonien Singh)
Following Ceti Alpha VI's accidental destruction by a top secret research team on starbase 47-Vanguard, Starfleet forged new charts of the Ceti Alpha system to cover up their experiments, pretending that Ceti Alpha V was actually Ceti Alpha IV. (VAN novel: Storming Heaven)
- Ceti Alpha was part of the battle map of Conquest. The novelization of The Wrath of Khan by Vonda N. McIntyre referred to the system as its real-life scientific name Alpha Ceti until the work was reprinted in Duty, Honor, Redemption in 2003.
